CUTTING AND FOLDING MACHINE.

Specification of Letters Patent. Patented June 22,1920,

lpplication'filed September 25, 1917. Serial No.193,090.

To all whom it may concern:

Be it known that I, HENRY E. LEONARD, a citizen of the United States,and resident of the borough of Brooklyn, in the city and State of NewYork, have invented a new and useful Improvement in Cutting and FoldingMachines, of which the following is a specification.

In cutting and folding machines there'is a tendency of the advanceedgeof the web from whichthe sheet has just been cut, to follow aroundone of the cutters, thus tending to curl the advance edge of the sheetout of its normal path from the cutters to the guides or frictionrollers on its way to the grippers of the collecting or foldingcylinder.

My invention includes means for imparting longitudinal stiffness to thetraveling web to insure its positive and accurate feeding to register.This stiffness is imparted to the web longitudinally of its travel bymeans, such for instance as guides arranged in staggered order fordeflecting portions of the web to opposite sides of a median line. meanssuch as pairs of guides, being provided for guiding the side edges ofthe web along said median line. i

A practical embodiment of my invention is represented in theaccompanying drawings in which, I

Figure 1 is a detail face view of that part of a cutting and foldingmachine which includes my invention, the web beingshown in connectiontherewith.

Fig. 2 is a transverse section taken in the plane of the line II-II ofFig. 1.

Fig. 3 is a section taken in the plane of the line IIIIII of Fig. 1.

Fig. 4 is a detail section taken in the plane of the line IV-IV of'Fig.1, and

Fig. 5 is a detail section taken in the plane of the line V-V of Fig. 1.

The web 1 is shown as passed over the web feed roll 2, and from thencedownwardly through pairs of guides 3, 4, and through the pair ofcoacting transverse web cutters 5, 6, to guides or friction rollers andgrippers (not shown). The member 3 of each pair of guides is mounted onthe bar 7 and the member 4 of each pair of guides is mounted on the bar8. The lower ends of one of the outside pairs of guides which engage theside edges of the web, are arranged to guide these side edges of the webalong a median line through the cutters. The intermediate pairs ofguides are arranged in staggered order for deflecting portions of theweb longitudinally of its travel between its side edges to the oppositesides of the median line through the cutters, thus longitudinallystiffening the web to insure its positive andaccurate feeding to theguides or friction rollers and grippers by eliminating any curling ortransverse waving action .of the web.

It is evident that various changes may be resorted to in theconstruction, form and arrangement of the several parts withoutdeparting from the spirit and scope of my invention, and hence I do notwish to limit myself to the particular embodiment shown and described,but

What I claim is:' Y

1. In a machine of the character described. transverse web cutters,means for feeding a web therethrough, and means in advance of thecutters, for oppositely deflecting portions of the web longitudinally ofits travel as it passes through the cutters, to stiffen the web forinsuring its positive and accurate feeding to register.

2. In a machine of the character described. transverse web cutters,means for feeding a web therethrough, and pairs of coacting guidesarranged in staggered order -in advance of the cutters, foroppositelvdeflecting portions of the web longitudinally of its travel asit passes through the cutters, to stiffen the web for insuring itspositive and accurate feeding to register.

3. In a machine of the character described, a pair of coactingtransverse web cutters. means for feeding a web therethrough and,

means in advance of the cutters. for deflecting portions of the weblongitudinally of its travel as it passes through the cutters, toopposite sides of a median line through the cutters for insuring itspositive and accurate feeding to register.

4. In a machine of the character described, a pair of coactingtransverse web cutters, means for feeding a web therethrough, and pairsof coacting guides arranged in staggered order in advance of thecutters, for deflecting portions of the web longitudinally of its travelas it passes through the cutters, to opposite sides of a median linethrough the cutters for insuring its positive and ac-v curate feeding toregister.

5. In a machine of the character described, a pair of coactingtransverse Web cutters, means for feeding a web therethrough, means inadvance of the cutters, for defiecting portions of the weblongitudinally of its travel between its side edges to opposite sides ofa median line through the cutters and means for guiding the side edgesof the Web along said medianline through the cutters.

6. In a machine of the character described, a pair of coactingtransverse web cutters, means for feeding a Web therethrough, pairs ofcoacting guides arranged in staggered order in advance of the cutters,for deflecting portions of the web longitudinally of.

its travel between its side edges to opposite sides of a median linethrough the cutters, and pairs of coacting guides for guiding the sideedges of the Web along said median line through the cutters. I

7. In a machine of the character described, a web feed roll, a pair ofcoacting transverse web cutters and means interposed between the Webfeed roll and cutters for imparting a zigzagform to the Web transverselyof its travel to longitudinally stiffen the web for insuring itspositive and accurate feeding to register.

8. In a machine of the character described, a Web feed roll, a pair ofcoacting transverse web cutters, and pairs of coacting guides arrangedin staggered order and interposed between the web feed roll and cuttersfor imparting a zigzag form to the web transversely of its travel tolongitudinally stifien the Web for insuring its positive and accuratefeeding to register.

In testimony that I claim the foregoing as my invention, I have signedmy name this 21st day of September, 1917. i

HENRY E. LEONARD
